Application filed June 2, 1910. Serial No. 564,615.

I 1% all whom "it may concern:

Be it known that Ll-l'ownnn M. Banana,

- a citizen of the United States, and resident of which the following isa specification.

This invention relates to improvements in printing machinery and is more"particularly directed to improvements 1:; the inking mechanismtherefor.

In inking mechanisms where the fountain roll is held stationaryduringthe intervals between its intermittent rotary move.

-ments, there is a tendency on the part of the ink es eciall where ver Yheav ink is used.,'

to draw away from the fountainroll and thus interfere with the properdeposit of the ink upon the doctor roll. I have discovered that Shyimparting to the fountain roll a continuous movementwith a slow movementin the intervals between the more rapidmovements imparted to thefountain roll at the time the doctor roll is in engage- 'ment therewith,I am enabled to secure a uniform deposit of the ink upon the doctor,roll, the continuous movement of the fountain roll preventing thisdrawing away of the ink as hereinabovestateds The object of my inventionis to provid mechanism for imparting this continuous slow movement andintermittent faster movement to the fountain roll, the mechanism beingso arranged that the "device for driving the roll continuously may bedisconn cted so as to permit the fountain roll to be drivenintermittently with stops between its movements, or to dis contact thedevice for driving the fountain roll intermittently for permitting thecontinuous slow movement of the fountain roll. For instance, withcertain qualities of ink it may be advisable to simply drive thefountain r'oll intermittently with stops between its movements, or itmay be desirable where only a very light deposit of color is required,to drive the fountain roll continuously with a slow movement. 1

A further object is to provide means for lengthening or shortening thestops in the intermittent movement of the fountain roll. This inventionis shown as applied to a multi-color printing press. A practicalembodiment of my invention This clu is represented in the accompanyingdrawings in which,

Figure 1 represents in front elevation, with the intermediate portionbroken away, so much of an inking mechanism and its operating parts aswill give a "clear understanding of my invention. Fi 2 represents thesame in top plan. Fig. firepresents the mechanism inside elevation withportions of the supporting frame shown in connection therewith. Fig. 3is a detail view showing the pawl carrying lever with the means forimparting the intermittent movement swung to the limit of its rearwardmovement. Fig. I

at isa detail vertical section taken in the plane. of the line AA ofFig. 1, looking in the direction of the arrows. Fig. 5 is a detaillongitudinal section through the-de vice for clutching the fountain rollshaft to and releasing it from the continuous feed device, and Fig. 6 isa transverse section through the same.

A suitable frame39 forms; a support for the ink fountain 4:6. Thefountainrol-l is denoted by 128 and its shaftby 176, which shaft ismounted in suitable half bearings in the ends of the ink fountain 46 andthe caps 177,118.

ltlanually operated means for rotating the fountain roll 1%, comprises aspur-gear 179 fixed to the shaft 176, which spur gear is engaged by apinion 1830 fixed on a shaft 181 carrying a crank handle 182. A shaft183 is mounted in suitable hearings in the side frame 39 in alinementwith the fountain roll shaft 176, adjacent to one end thereof and aclutch member 184- is arranged to be moved into and outv ofinterlockingengagementwith the inner end of the shaft 183.

connection 185 at all times with sleeve 1.86 keyed to the fountainrollshaft 176. This clutch member l84t-has a sliding movement on thesleeve 186 sufficientto permit the clutch member 18 to be moved entirelyout 1 of interlocking connection with. the end. of

the'shaft 183 when so desired. A manually. operated lever 187 is pivotedat 188 on the fountain frame 189, the inner end of which lever isprovided with a shoe 190 located in a circumferential groove 191 in theclutch member 1841-. A spring 192tends to push the lever 18'? in adirection to disconnect the clutch member 184: from the shaft 183. Aswinging latch 198 is arranged to drop into member 18% has a rollerclutch its position to hold the lever 181 against the tension of thespring 192 -with the clutch member 184 in interlocking engagement withthe shaft 183. The shaft 183 is provided at its outer end with a gear141 which meshes 'with a worm 140 fixed to a diagonal shaft 139 mountedin suitable upper and lower bearings.194*,'195*, on the frame 39.- B-

tary movement is imparted to the shaft 139 r from the shaft 113 throughthe gears- The step by step movement is imparted to the fountain roll,128 by the following device. A ratchet wheel 194 is' fixed to thefountain rollshaft 176. A pawl carrying lever 195 and a pawl operatinglever 196 are keyed to the stud shaft 176*, the pawl 197* being pivotedto the lever 195 in position to travel along the ratchet wheel 194, whenmoved in one direction and to interlock with the ratchet wheel and moveit and thereby the fountain roll, when moved in the opposite direction.A stop 198 is arranged to limit the rearward movement of the pawl 197,

which stop 198 is adjustably secured to the frame 39 by a pin and slotengagement 1.99,

200, therewith, a clamp screw'201 having an engagement with the pin- 199for securing the stop 198 in its desired position. A'spring 202 engagesthe frame 39 and the pawl operating lever 196, which spring tends tohold the pawl 197 at the limit of its rearward movement. A rocking arm203 is loosely mounted upon the stud shaft 176* and the free end of thearm 203 is oonnected'to a crank disk 204 on the cam shaft 122 by aconnecting rod 205. This connecting rod 205 is adjustably secured to thecrank disk 204 by a pin and slot connection 206, 107, a nut 208 beingprovidedfor clamping the connecting rod 205in the desired position onthe crank disk 204, so as to determine the throw'of the arm 203. Thisarm 203 is arranged to engage a lug 209 on the lever 196, for moving thelevers 195,

196, and thereby thepawl 197 during a greater or lesser portion of thedownward movement of the arm 203,'according to the position of the stop198 and the adjustable connection of the rod 205 with the crank diskThe' doctor roll 54 maybe alternately engaged with the ink transfer roll58 and the fountain 1 roll 128 by the following-device; The doctor rollcarrying lever comprises arms 210 fixed to the shaft 211, in which armsthe doctorro'll is mounted. Other arms 212, 213 are fixed to the shaft211 and are provided with studs or rollers 214, 215, ar-

ranged to be engaged by a cam 216 fixed on the cam shaft 122. A suitablespring 217 is interposed between a fixed abutment 218 on the frame 39and a collar 219 on the rod 220 connected to the free end of an arm 221fixed to the shaft 211 for holding the stud or roller 214 in engagementwith the cam 216.

In'operation, if it 'is desired to drive the fountain roll continuouslyat a slow speed, the clutch member 184 is interlocked with ,the shaft183 and the-pawl 197 is thrown back out of engagement with its ratchetwheel 194. If it is desired'to drive the fountain roll intermittentlywith periods'of rest between its movements, the pawl 197 is engaged withits ratchet wheel 194' and the clutch member 184 is disconnected fromthe -sha ft 183. If-it is desired to impart to the,

fountain -roll a combination of a slow continuous movement with anintermittent higher movement, the clutch. member 184 is interlocked withtheishaft 183 and the pawl 197 is dropped into engagement with itsratchet wheel 194.

The roller clutch connection between the clutch member 184 and thesleeve 186 on the shaft 176, permits the shaft 176 to be moved morerapidly than the movement of the shaft 183 at the periods of theintermittent higher movement.

parted to the fountain roll may be provided for-by adjusting the stop198 so as to engage the pawl lever at any desired point in the upwardmovement of'theroking' arm 203, the

balance of the movement of the arm being of no effect on the pawllever." The movementof this rocking arm 203 can also be adjusted byproperly positioningthe connecting rod 205 on the crank disk 204, asherein:

before described.

It is evidentthat various changes might beresorted to in theconstruction, form and ar-, rangement of the several parts without de-'parting from the spirit and scope of my in- The amount of eachrapidmovementimevention; hence I do not wish to. limit myself g strictly tothe structure herein set forth, but
